In situ visualization of hydrothermal processes in process water cycles with the D-System.

Ques­tion:
How easy is the dis­play to read?

An­swer:
The touch dis­play has a self-lu­mi­nous LED TFT with a res­o­lu­tion of 800x480 pixels.

Ques­tion:
What val­ues does the D‑System display?

An­swer:
In­let tem­per­a­ture, in­let pres­sure, re­turn tem­per­a­ture, re­turn pres­sure, flow rate, flow, en­er­gy, pres­sure dif­fer­ences, tem­per­a­ture dif­fer­ences, syn­chro­niza­tion sig­nal, process lim­its and sys­tem messages.

Ques­tion:
Can the mea­sur­ing mod­ule record the da­ta with­out the display?

An­swer:
No, with­out the dis­play there is no func­tion and can on­ly record when the mea­sur­ing mod­ule is con­nect­ed to the D‑System.

Ques­tion:
How is the mea­sure­ment da­ta displayed?

An­swer:
The op­er­a­tor can choose be­tween dif­fer­ent views, scheme, list, ana­log and graph.

Ques­tion:
Can the D‑System be used to check a tem­per­a­ture con­trol unit, for example?

An­swer:
Yes, in prin­ci­ple every­thing can be test­ed that fits the mea­sur­ing range of the mea­sur­ing module.

Ques­tion:
When check­ing a mold cir­cuit, is it pos­si­ble to see the in­flu­ence of the melt in the re­turn temperature?

An­swer:
Yes, pro­vid­ed that the en­er­gy in­tro­duced in­to this cir­cuit is suf­fi­cient, the in­flu­ence be­comes visible.

Ques­tion:
Can I syn­chro­nize an in­jec­tion mold­ing ma­chine with the D‑system?

An­swer:
Yes, if a po­ten­tial-free con­tact is set at e.g. start in­jec­tion and this is con­nect­ed to the SUBD9 on the D‑system, the process can be record­ed with the mea­sure­ment da­ta and can be found in the log file.

Ques­tion:
In what form do I re­ceive the mea­sure­ment da­ta? How can I eval­u­ate the mea­sure­ment data?

An­swer:
A .csv file is saved on e.g. a USB stick, which can be opened via e.g. MS Excel.

Ques­tion:
What da­ta can be found in the log file?

An­swer:
The fol­low­ing mea­sure­ment da­ta are list­ed: date, time, in­put tem­per­a­ture, out­put tem­per­a­ture, in­put pres­sure, out­put pres­sure, flow, warn­ing, lim­it, DI01

Ques­tion:
Which con­nec­tions does the ma­sur­ing mod­ule have?

An­swer:
The mea­sur­ing mod­ule type 1 has 4x G3/4“ fe­male threads.

Ques­tion:
How long can I work with the D‑system in bat­tery mode?

An­swer:
The D‑system can be op­er­at­ed for ap­prox. 4 h — 5 h in bat­tery mode.

Ques­tion:
Can I use the D‑system while it is charg­ing the battery?

An­swer:
If the ca­pac­i­ty of the bat­tery is above 10%, it is pos­si­ble to charge and use the sys­tem at the same time.

Ques­tion:
Can I re­place the battery?

An­swer:
The bat­tery is per­ma­nent­ly in­stalled and can on­ly be re­placed by Hotset GmbH.
